Patch notes: generative bells with Marbles

May has me chasing one sound: bells that ring out on their own, never repeating, like wind chimes you didn't hang. This is a "set it up and walk away" patch — it'll play itself for hours. It's become my favorite thing to leave running while I make coffee.

The heart of it is Mutable Instruments Marbles generating the pitches and the rhythm, feeding Plaits in its bell/modal model.

Patch sheet:

• Marbles t2 → Plaits trig. This is your rhythm. Set the t rate medium, bias toward sparse.
• Marbles X1 → Plaits V/OCT. The Spread knob controls how wide the melodic range wanders.
• Marbles DEJA VU around 11 o'clock — enough repetition that it feels intentional, enough randomness that it never loops.
• Plaits model on bells, harmonics high, decay long.
• A short slap delay and a big shimmer reverb on the output. The shimmer is doing a lot of the magic.

Tiny moves on Spread and DEJA VU completely change the mood, from sparse and meditative to busy and music-box-like.

Recorded ten minutes of it drifting: generative bells.
